Abstract : This research project carried out a tentative study of automatic satellite navigation based on a stellar sensor. The study shows that with a known starlight refraction model of the Earth's atmosphere, automatic satellite navigation can be realized through starlight refraction measurement or obscuration time measurement, without the necessity of an accurate attitude determination. In the study report, a basic related navigation algorithm was proposed, the effect of errors was discussed, and several characteristics of such navigation were revealed through mathematic simulation calculations.
